Ancient Blood Chemicals Offer New Insights into Fossil Bones
Scientists are now able to glean new information from fossil bones by analyzing tiny traces of ancient blood chemicals, according to a January 31, 2026, article in Phys.org. Researchers can learn a great deal about a body's health from these blood tests, mirroring the utility of blood samples in modern medicine.
The article, reviewed by Andrew Zinin and edited by Lisa Lock, highlights the work of Timothy G. Bromage and was originally published in Nature (DOI: 10.1038/s41586-025-09843-w). The research utilizes blood tests as tools to understand the large molecules present in fossil specimens, offering a picture of the health and life of ancient creatures.
